Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Rexford Industrial Realty, Inc. is a self-administered and self-managed full-service real estate investment trust (“REIT”) focused on owning and operating industrial properties in Southern California infill markets. We were formed as a Maryland corporation on January 18, 2013 and Rexford Industrial Realty, L.P. (the “Operating Partnership”), of which we are the sole general partner, was formed as a Maryland limited partnership on January 18, 2013. Through our controlling interest in our Operating Partnership and its subsidiaries, we own, manage, lease, acquire and develop industrial real estate located in Southern California infill markets, and from time to time, acquire or provide mortgage debt secured by industrial property. As of December 31, 2018 , our consolidated portfolio consisted of 176 properties with approximately 21.3 million rentable square feet. In addition, we currently manage an additional 20 properties with approximately 1.2 million rentable square feet. The terms “us,” “we,” “our,” and the “Company” as used in these financial statements refer to Rexford Industrial Realty, Inc. and its subsidiaries (including our Operating Partnership).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying financial statements are the consolidated financial statements of Rexford Industrial Realty, Inc. and its subsidiaries, including our Operating Partnership. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements. Under consolidation guidance, we have determined that our Operating Partnership is a variable interest entity because the holders of limited partnership interests do not have substantive kick-out rights or participating rights. Furthermore, we are the primary beneficiary of the Operating Partnership because we have the obligation to absorb losses and the right to receive benefits from the Operating Partnership and the exclusive power to direct the activities of the Operating Partnership. As of December 31, 2018 and 2017 , the assets and liabilities of the Company and the Operating Partnership are substantially the same, as the Company does not have any significant assets other than its investment in the Operating Partnership. The accompanying consolidated financial statements have been prepared in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) as established by the Financial Accounting Standards Board (“FASB”) in the Accounting Standards Codification including modifications issued under Accounting Standards Updates (“ASUs”). Any reference to the number of properties, buildings and square footage are unaudited and outside the scope of our independent auditor’s audit of our financial statements in accordance with the standards of the Public Company Accounting Oversight Board. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents include all cash and liquid investments with an initial maturity of three months or less. The carrying amount approximates fair value due to the short-term maturity of these investments. Restricted Cash Restricted cash is generally comprised of cash proceeds related to property dispositions that are being held by qualified intermediaries for purposes of facilitating tax-deferred like-kind exchanges under Section 1031 of the Internal Revenue Code (“1031 Exchange”). As of December 31, 2018 , we did no t have a balance in restricted cash. As of December 31, 2017 , the $250,000 balance in restricted cash was related to a non-refundable deposit we received in connection with the execution of a contract to sell our property located at 700 Allen Avenue. Restricted cash balances are included with cash and cash equivalents balances as of the beginning and ending of each period presented in the consolidated statements of cash flows. The following table provides a reconciliation of our cash and cash equivalents and restricted cash as of December 31, 2018 and 2017 (in thousands): December 31, 2018 December 31, 2017 Cash and cash equivalents $ 180,601 $ 6,620 Restricted cash — 250 Cash, cash equivalents and restricted cash $ 180,601 $ 6,870 Investment in Real Estate Acquisitions Effective January 1, 2017, we adopted Accounting Standards Update (“ASU”) 2017-01, Business Combinations - Clarifying the Definition of a Business (“ASU 2017-01’), which provides a new framework for determining whether transactions should be accounted for as acquisitions of assets or businesses. Under ASU 2017-01, when substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single identifiable asset or a group of similar assets, the set of assets and activities is not a business. ASU 2017-01 also revises the definition of a business to include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create an output. We evaluated the acquisitions that we completed during the years ended December 31, 2018 and 2017 , and determined that under this framework these transactions should be accounted for as asset acquisitions. We expect that most of our property acquisitions will generally not meet the revised definition of a business because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets or because the acquisition does not include a substantive process. For acquisitions that are accounted for as asset acquisitions, because they do not meet the business combination accounting criteria, we allocate the cost of the acquisition, which includes the purchase price and associated acquisition transaction costs, to the individual assets acquired and liabilities assumed on a relative fair value basis. These individual assets and liabilities typically include land, building and improvements, tenant improvements, intangible assets and liabilities related to above and below market leases, intangible assets related to in-place leases, and from time to time, assumed debt. As there is no measurement period concept for an asset acquisition, the allocated cost of the acquired assets is finalized in the period in which the acquisition occurs. We determine the fair value of the tangible assets of an acquired property by valuing the property as if it were vacant. This “as-if vacant” value is estimated using an income, or discounted cash flow, approach that relies upon Level 3 inputs, which are unobservable inputs based on the Company’s assumptions about the assumptions a market participant would use. These Level 3 inputs include discount rates, capitalization rates, market rents and comparable sales data for similar properties. Estimates of future cash flows are based on a number of factors including historical operating results, known and anticipated trends, and market and economic conditions. In calculating the “as-if-vacant” value for acquisitions completed during the year ended December 31, 2018 , we used discount rates ranging from 5.50% to 7.50% and capitalization rates ranging from 4.25% to 6.25% . In determining the fair value of intangible lease assets or liabilities, we also consider Level 3 inputs. Acquired above- and below-market leases are valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the term of any below-market fixed rate renewal options for below-market leases, if applicable. The estimated fair value of acquired in-place at-market tenant leases are the costs that would have been incurred to lease the property to the occupancy level of the property at the date of acquisition. Such estimates include the value associated with leasing commissions, legal and other costs, as well as the estimated period necessary to lease such property to its occupancy level at the time of its acquisition. In determining the fair value of acquisitions completed during the year ended December 31, 2018 , we used an estimated average lease-up period ranging from six to twelve months. The difference between the fair value and the face value of debt assumed in connection with an acquisition is recorded as a premium or discount and amortized to “interest expense” over the life of the debt assumed. The valuation of assumed liabilities is based on our estimate of the current market rates for similar liabilities in effect at the acquisition date. Capitalization of Costs We capitalize direct costs incurred in developing, renovating, rehabilitating and improving real estate assets as part of the investment basis. This includes certain general and administrative costs, including payroll, bonus, and noncash equity compensation of the personnel performing development, renovations and rehabilitation if such costs are identifiable to a specific activity to get the real estate asset ready for its intended use. During the development and construction periods of a project, we also capitalize interest, real estate taxes and insurance costs. We cease capitalization of costs upon substantial completion of the project, but no later than one year from cessation of major construction activity. If some portions of a project are substantially complete and ready for use and other portions have not yet reached that stage, we cease capitalizing costs on the completed portion of the project but continue to capitalize for the incomplete portion of the project. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. We capitalized interest costs of $2.1 million , $1.7 million and $1.7 million during the years ended December 31, 2018 , 2017 and 2016 , respectively. We capitalized real estate taxes and insurance aggregating $0.9 million , $1.2 million , and $0.8 million and during the years ended December 31, 2018 , 2017 and 2016 , respectively. We capitalized compensation costs for employees who provide construction services of $2.2 million , $1.9 million and $1.0 million during the years ended December 31, 2018 , 2017 and 2016 , respectively. Depreciation and Amortization Real estate, including land, building and land improvements, tenant improvements, furniture, fixtures and equipment and intangible lease assets and liabilities are stated at historical cost less accumulated depreciation and amortization, unless circumstances indicate that the cost cannot be recovered, in which case, the carrying value of the property is reduced to estimated fair value as discussed below in our policy with regard to impairment of long-lived assets. We estimate the depreciable portion of our real estate assets and related useful lives in order to record depreciation expense. The values allocated to buildings, site improvements, in-place lease intangibles and tenant improvements are depreciated on a straight-line basis using an estimated remaining life of 10 - 30 years for buildings, 5 - 20 years for site improvements, and the shorter of the estimated useful life or respective lease term for in-place lease intangibles and tenant improvements. As discussed above in— Investments In Real Estate — Acquisitions , in connection with property acquisitions, we may acquire leases with rental rates above or below the market rental rates. Such differences are recorded as an acquired lease intangible asset or liability and amortized to “rental revenues” over the remaining term of the related leases. Our estimate of the useful life of our assets is evaluated upon acquisition and when circumstances indicate a change in the useful life, which requires significant judgment regarding the economic obsolescence of tangible and intangible assets. Assets Held for Sale We classify a property as held for sale when all of the criteria set forth in ASC Topic 360: Property, Plant and Equipment (“ASC 360”) have been met. The criteria are as follows: (i) management, having the authority to approve the action, commits to a plan to sell the property; (ii) the property is available for immediate sale in its present condition, subject only to terms that are usual and customary; (iii) an active program to locate a buyer and other actions required to complete the plan to sell have been initiated; (iv) the sale of the property is probable and is expected to be completed within one year; (v) the property is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (vi) actions necessary to complete the plan of sale indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. At the time we classify a property as held for sale, we cease recording depreciation and amortization. A property classified as held for sale is measured and reported at the lower of its carrying amount or its estimated fair value less cost to sell. See Note 12. Deferred Leasing Costs We capitalize costs directly related to the successful origination of a lease. These costs include leasing commissions paid to third parties for new leases or lease renewals, as well as an allocation of compensation costs, including payroll, bonus and non-cash equity compensation, of employees who spend time on lease origination activities. In determining the amount of compensation costs to be capitalized for these employees, allocations are made based on estimates of the actual amount of time spent working on successful leases in comparison to time spent on unsuccessful origination efforts. We capitalized compensation costs for these employees of $1.0 million , $1.0 million and $0.6 million during the years ended December 31, 2018 , 2017 and 2016 , respectively. Impairment of Long-Lived Assets In accordance with the provisions of the Impairment or Disposal of Long-Lived Assets Subsections of ASC 360, we assess the carrying values of our respective long-lived assets, including goodwill, whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Recoverability of real estate assets is measured by comparison of the carrying amount of the asset to the estimated future undiscounted cash flows. To review real estate assets for recoverability, we consider current market conditions as well as our intent with respect to holding or disposing of the asset. The intent with regard to the underlying assets might change as market conditions and other factors change. Fair value is determined through various valuation techniques, including discounted cash flow models, applying a capitalization rate to estimated net operating income of a property, quoted market values and third party appraisals, where considered necessary. The use of projected future cash flows is based on assumptions that are consistent with estimates of future expectations and the strategic plan used to manage our underlying business. If our analysis indicates that the carrying value of the real estate asset is not recoverable on an undiscounted cash flow basis, we will recognize an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the real estate property. Assumptions and estimates used in the recoverability analyses for future cash flows, discount rates and capitalization rates are complex and subjective. Changes in economic and operating conditions or our intent with respect to our investment that occur subsequent to our impairment analyses could impact these assumptions and result in future impairment of our real estate properties. Investment in Unconsolidated Real Estate Entities Investments in unconsolidated real estate entities in which we have the ability to exercise significant influence (but not control) are accounted for under the equity method of investment. Under the equity method, we initially record our investment at cost, and subsequently adjust for equity in earnings or losses and cash contributions and distributions. Any difference between the carrying amount of these investments on the balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in income (loss) from unconsolidated real estate over the life of the related asset. Under the equity method of accounting, our net equity investment is reflected within the consolidated balance sheets, and our share of net income or loss from the joint ventures is included within the consolidated statements of operations. Furthermore, distributions received from equity method investments are classified as either operating cash inflows or investing cash inflows in the consolidated statements of cash flows using the “nature of the distribution approach,” in which each distribution is evaluated on the basis of the source of the payment. See Note 11. Income Taxes We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) commencing with our initial taxable year ended December 31, 2013. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the Code relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and were unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax. In addition, we are subject to taxation by various state and local jurisdictions, including those in which we transact business or reside. Our non-taxable REIT subsidiaries, including our Operating Partnership, are either partnerships or disregarded entities for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities and flow-through entities such as partnerships is reportable in the income tax returns of the respective equity holders. Accordingly, no income tax provision is included in the accompanying consolidated financial statements for the years ended December 31, 2018 , 2017 and 2016 . We periodically evaluate our tax positions to determine whether it is more likely than not that such positions would be sustained upon examination by a tax authority for all open tax years, as defined by the statute of limitations, based on their technical merits. As of December 31, 2018 and 2017 , we have not established a liability for uncertain tax positions. Derivative Instruments and Hedging Activities ASC Topic 815: Derivatives and Hedging (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. As required by ASC 815, we record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, and whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. We may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting does not apply or we elect not to apply hedge accounting. See Note 7. Revenue Recognition Our primary sources of revenue are rental income, tenant reimbursements, other income, management, leasing and development services and gains on sale of real estate. Rental Income Minimum annual rental revenues are recognized in rental income on a straight-line basis over the term of the related lease, regardless of when payments are contractually due. Rental revenue recognition commences when the tenant takes possession or controls the physical use of the leased space. Lease termination fees, which are included in rental income, are amortized over the remaining term of the lease until we have no continuing obligation to provide services to such former tenant. Tenant Reimbursements Our lease agreements with tenants generally contain provisions that require tenants to reimburse us for certain property expenses. Estimated reimbursements from tenants for real estate taxes, common area maintenance and other recoverable operating expenses are recognized as revenues in the period that the expenses are incurred. Subsequent to year-end, we perform final reconciliations on a lease-by-lease basis and bill or credit each tenant for any cumulative annual adjustments. Other Income Other income primarily consists of late payment fees and other miscellaneous tenant related revenues. Management, leasing and development services We provide property management services and leasing services to related party and third-party property owners, the customer, in exchange for fees and commissions. Property management services include performing property inspections, monitoring repairs and maintenance, negotiating vendor contracts, maintaining tenant relations and providing financial and accounting oversight. For these services, we earn monthly management fees, which are based on a fixed percentage of each managed property’s monthly tenant cash receipts. We have determined that control over the services is passed to the customer simultaneously as performance occurs. Accordingly, management fee revenue is earned as the services are provided to our customers. Leasing commissions are earned when we provide leasing services that result in an executed lease with a tenant. We have determined that control over the services is transferred to the customer upon execution of each lease agreement. We earn leasing commissions based on a fixed percentage of rental income generated for each executed lease agreement and there is no variable income component. Gain or Loss on Sale of Real Estate We account for dispositions of real estate properties, which are considered nonfinancial assets, in accordance with ASC 610-20: Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets and recognize a gain or loss on sale of real estate upon transferring control of the nonfinancial asset to the purchaser, which is generally satisfied at the time of sale. If we were to conduct a partial sale of real estate by transferring a controlling interest in a nonfinancial asset, while retaining a noncontrolling ownership interest, we would measure any noncontrolling interest received or retained at fair value, and recognize a full gain or loss. If we receive consideration before transferring control of a nonfinancial asset, we recognize a contract liability. If we transfer control of the asset before consideration is received, we recognize a contract asset. Valuation of Receivables We may be subject to tenant defaults and bankruptcies that could affect the collection of outstanding receivables. In order to mitigate these risks, we perform credit reviews and analyses on prospective tenants before significant leases are executed and on existing tenants before properties are acquired. We specifically analyze aged receivables, customer credit-worthiness, historical bad debts and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. As a result of our periodic analysis, we maintain an allowance for estimated losses that may result from the inability of our tenants to make required payments. This estimate requires significant judgment related to the lessees’ ability to fulfill their obligations under the leases. We believe our allowance for doubtful accounts is adequate for our outstanding receivables for the periods presented. If a tenant is insolvent or files for bankruptcy protection and fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the net outstanding balances, which include amounts recognized as straight-line revenue not realizable until future periods. Rents and other receivables, net and deferred rent receivables, net consisted of the following as of December 31, 2018 and 2017 (in thousands): December 31, 2018 2017 Rents and other receivables $ 6,772 $ 5,369 Allowance for doubtful accounts (1,828 ) (1,705 ) Rents and other receivables, net $ 4,944 $ 3,664 Deferred rent receivable $ 22,420 $ 15,912 Allowance for doubtful accounts (192 ) (86 ) Deferred rent receivable, net $ 22,228 $ 15,826 We recorded the following provision for doubtful accounts, including amounts related to deferred rents, as a reduction to rental revenues in our consolidated statements of operations for the years ended December 31, 2018 , 2017 and 2016 , (in thousands): Year Ended December 31, 2018 2017 2016 Provision for doubtful accounts $ 1,203 $ 1,118 $ 1,233 Debt Issuance Costs Debt issuance costs related to a recognized debt liability are presented in the balance sheet as a reduction from the carrying value of the debt liability. This offset against the debt liability is treated similarly to a debt discount, which effectively reduces the proceeds of a borrowing. For line of credit arrangements, we present debt issuance costs as an asset and amortize the cost over the term of the line of credit arrangement. See Note 5. Equity Based Compensation We account for equity based compensation in accordance with ASC Topic 718 Compensation – Stock Compensation . Total compensation cost for all share-based awards is based on the estimated fair market value on the grant date. For share-based awards that vest based solely on a service condition, we recognize compensation cost on a straight-line basis over the total requisite service period for the entire award. For share-based awards that vest based on a market condition, we recognize compensation cost on a straight-line basis over the requisite service period of each separately vesting tranche. For share-based awards that vest based on a performance condition, we recognize compensation cost based on the number of awards that are expected to vest based on the probable outcome of the performance condition. Compensation cost for these awards will be adjusted to reflect the number of awards that ultimately vest. Forfeitures are recognized in the period in which they occur. See Note 14. Equity Offering Costs Underwriting commissions and offering costs related to our common stock issuances have been reflected as a reduction of additional paid-in capital. Underwriting commissions and offering costs related to our preferred stock issuances have been reflected as a direct reduction of the preferred stock balance. Earnings Per Share We calculate earnings per share (“EPS”) in accordance with ASC 260 – Earnings Per Share (“ASC 260”). Under ASC 260, nonvested share-based payment awards that contain non-forfeitable rights to dividends are participating securities and, therefore, are included in computing basic EPS pursuant to the two-class method. The two-class method determines EPS for each class of common stock and participating securities according to dividends declared (or accumulated) and their respective participation rights in undistributed earnings. Basic EPS is calculated by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted EPS is calculated by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding determined for the basic EPS computation plus the effect of any dilutive securities. We include unvested shares of restricted stock and unvested LTIP units in the computation of diluted EPS by using the more dilutive of the two-class method or treasury stock method. We include unvested performance units as contingently issuable shares in the computation of diluted EPS once the market criteria are met, assuming that the end of the reporting period is the end of the contingency period. Any anti-dilutive securities are excluded from the diluted EPS calculation. See Note 15. Segment Reporting Management views the Company as a single segment based on its method of internal reporting in addition to its allocation of capital and resources. Adoption of New Accounting Pronouncements Revenue Recognition (ASC 606) On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), and subsequently issued additional ASUs which provide practical expedients, technical corrections and clarification of the new standard (collectively “ASC 606”). ASC 606 establishes principles for reporting the nature, amount, timing and uncertainty of revenues and cash flows arising from an entity’s contracts with customers. The core principle of the new standard is that an entity recognizes revenue to represent the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Effective January 1, 2018, we adopted ASC 606 using the modified retrospective approach. We evaluated each of our revenue streams to determine the sources of revenue that are impacted by ASC 606 and concluded that management services and leasing services fall within the scope of ASC 606. We evaluated the impact of ASC 606 on the timing and pattern of revenue recognition for our management and leasing services contracts and determined there was no change in the timing or pattern of revenue recognition for these contracts as compared to prior accounting practice. Accordingly, the adoption of ASC 606 did not have an impact on our consolidated financial statements. See “Revenue Recognition” above for further details. Derecognition of Non-Financial Assets On February 22, 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05). ASU 2017-05 clarifies the scope of asset derecognition and adds further guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with non-customers. Effective January 1, 2018, we adopted ASU 2017-05 using the modified retrospective approach. There was no cumulative effect adjustment recorded to retained earnings as of January 1, 2018 as a result of the adoption of ASU 2017-05. Derivatives On August 28, 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). ASU 2017-12 simplifies hedge accounting by eliminating the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. For cash flow hedges, ASU 2017-12 requires all changes in the fair value of the hedging instrument to be deferred in other comprehensive income and recognized in earnings at the same time that the hedged item affects earnings. ASU 2017-12 also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. ASU 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. Effective January 1, 2018, we early adopted ASU 2017-12 using the modified retrospective approach. We did not record a cumulative effect adjustment to eliminate ineffectiveness amounts as we did not have any ineffectiveness in our historical consolidated financial statements. In addition, certain provisions of ASU 2017-12 require modifications to existing presentation and disclosure requirements on a prospe

Investments, All Other Investments [Abstract]
Investments in Real Estate	Investments in Real Estate REIT Portfolio Acquisition On April 11, 2016, we entered into a stock purchase agreement (the “Stock Purchase Agreement”) to acquire a private real estate investment trust (the “private REIT”) that owned a portfolio of nine industrial properties totaling approximately 1.5 million rentable square feet (the “REIT Portfolio”) from a third-party seller in exchange for approximately $191.0 million in cash, exclusive of closing costs and credits (the “REIT Portfolio Acquisition”). On April 15, 2016, pursuant to the Stock Purchase Agreement, we consummated the transaction. As part of the REIT Portfolio Acquisition, we acquired 100% of the private REIT’s common stock and 575 of 700 issued and outstanding shares of the private REIT’s 12.5% cumulative non-voting preferred stock (the “preferred stock”). The remaining 125 shares of preferred stock, which were held by unaffiliated third parties, were not immediately redeemed by us and remained outstanding in order to help us comply with federal income tax regulations applicable to REITs. On June 22, 2017, we adopted a plan of liquidation and dissolution of the private REIT, and on December 31, 2017 , we completed the liquidation of the private REIT by distributing all assets to the Operating Partnership. As part of the liquidation process, we paid a liquidating distribution of $1,000 per share, or an aggregate liquidating distribution of $125,000 , as payment in full for the redemption of the remaining 125 share of preferred stock not held by us.

Contractual Debt Maturities The following table summarizes the contractual debt maturities and scheduled amortization payments, excluding debt discounts and debt issuance costs, as of December 31, 2018 , and does not consider extension options available to us as noted in the table above (in thousands): 2019 $ 158 2020 166 2021 566 2022 100,967 2023 282,518 Thereafter 376,741 Total $ 761,116 Fourth Amendment to Credit Agreement On January 16, 2018, we entered into the Fourth Amendment to Credit Agreement (the “Fourth Amendment”) to amend our Credit Agreement, dated as of January 14, 2016 (as amended from time to time) for our $225.0 million unsecured term loan facility (the “$225 Million Term Loan Facility”). Amounts outstanding under the $225 Million Term Loan Facility bear interest at a rate equal to, at our option, either (i) LIBOR plus an applicable margin that is based upon our leverage ratio or (ii) the Base Rate, as defined in the $225 Million Term Loan Facility, plus an applicable margin that is based on our leverage ratio. The Fourth Amendment decreases the applicable margin for LIBOR-based borrowings from a range of 1.50% to 2.25% per annum to a range of 1.20% to 1.70% per annum and decreases the applicable margin for Base Rate-based borrowings from a range of 0.50% to 1.25% per annum to a range of 0.20% to 0.70% per annum. If we obtain one additional investment grade rating by one or more of Standard & Poor's Financial Services (“S&P”) or Moody's Investor Services (“Moody’s”) to complement our current investment grade Fitch rating, we may elect to convert the pricing structure under the $225 Million Term Loan Facility to be based on such rating. Under this pricing structure, the Fourth Amendment decreases the applicable margin for LIBOR-based borrowings from a range of 1.40% to 2.35% per annum to a range of 0.90% to 1.75% per annum and decreases the applicable margin for Base Rate-based borrowings from a range of 0.40% to 1.35% per annum to a range of 0.00% to 0.75% per annum. $150 Million Term Loan Facility On May 22, 2018, we entered into a credit agreement for a senior unsecured term loan facility (the “$150 Million Term Loan Facility”) that initially permits aggregate borrowings of up to $150.0 million , the total of which we borrowed the same day at closing. Under the terms of the $150 Million Term Loan Facility, we may request additional incremental term loans in an aggregate amount not to exceed $100.0 million . Any increase in borrowings is subject to the satisfaction of specified conditions and the identification of lenders willing to make available such additional amounts. The maturity date of the $150 Million Term Loan Facility is May 22, 2025. Interest on the $150 Million Term Loan Facility is generally to be paid based upon, at our option, either (i) LIBOR plus an applicable Eurodollar rate margin or (ii) the Base Rate (which is defined as the highest of (a) the federal funds rate plus 0.50% , (b) the administrative agent’s prime rate or (c) the Eurodollar Rate plus 1.00% ), plus an applicable base rate margin. The applicable Eurodollar rate margin will range from 1.50% to 2.20% per annum for LIBOR-based borrowings and the applicable base rate margin will range from 0.50% to 1.20% per annum for Base Rate-based loans, depending on our leverage ratio. If we obtain one additional investment grade rating from one or more of S&P or Moody's to complement our current investment grade Fitch rating, we may elect to convert the pricing structure under the $150 Million Term Loan Facility to be based on such rating. Under this pricing structure, the applicable Eurodollar rate margin will range from 1.40% to 2.35% per annum and the applicable base rate margin will range from 0.40% to 1.35% per annum. We have the option to voluntarily prepay any amounts borrowed under the $150 Million Term Loan Facility in whole or in part at any time, subject to certain notice requirements. To the extent that we prepay all or any portion of a loan prior to May 22, 2020, we will pay a prepayment premium equal to (i) if such prepayment occurs prior to May 22, 2019, 2.00% of the principal amount so prepaid, and (ii) if such prepayment occurs on or after May 22, 2019, but prior to May 22, 2020, 1.00% of the principal amount so prepaid. Amounts borrowed under the $150 Million Term Loan Facility and repaid or prepaid may not be reborrowed. The $150 Million Term Loan Facility contains usual and customary events of default including defaults in the payment of principal, interest or fees, defaults in compliance with the covenants set forth in the credit agreement and other loan documentation, cross-defaults to certain other indebtedness, and bankruptcy and other insolvency defaults. If an event of default occurs and is continuing under the $150 Million Term Loan Facility, all outstanding principal amounts, together with all accrued unpaid interest and other amounts owing in respect thereof, may be declared immediately due and payable. Modification of $60 Million Term Loan On June 27, 2018, we entered into the Second Modification Agreement (the “Modification Agreement”) to amend our Term Loan Agreement, dated as of July 24, 2013 (as amended from time to time) for our $60.0 million term loan (the “$60 Million Term Loan”) The Modification Agreement, among other things, (i) extends the maturity date of the $60 Million Term Loan from August 1, 2019, to August 1, 2023, (ii) decreases the interest rate from LIBOR plus 1.90% per annum to LIBOR plus 1.70% per annum, (iii) provides for one 24-month extension option, subject to certain terms and conditions, and (iv) amends the repayment schedule of the $60 Million Term Loan by adding 36 months of interest only payments, followed by equal monthly payments of principal ($65,250 ), plus accrued interest until maturity. Note Purchase and Guarantee Agreement On July 13, 2017, we entered into a Note Purchase and Guarantee Agreement (the “NPGA”) for the private placement of $125.0 million of senior unsecured guaranteed notes, maturing on July 13, 2027, with a fixed annual interest rate of 3.93% (the “$125 Million Notes”). On July 13, 2017, we completed the issuance of the $125 Million Notes. Interest on the $125 Million Notes will be payable quarterly on the thirteenth day of January, April, July and October in each year, commencing on October 13, 2017. We may prepay at any time all or, from time to time, any part of the $125 Million Notes, in amounts not less than $2.5 million of the $125 Million Notes then outstanding at (i) 100% of the principal amount so prepaid and (ii) the Make-Whole Amount (as defined in the NPGA). Our obligations under the $125 Million Notes are fully and unconditionally guaranteed by us and certain of our subsidiaries. Loan Repayments On March 20, 2017, we repaid the $9.7 million outstanding balance on the 1065 Walnut Street mortgage loan in advance of the February 1, 2019 maturity date. In connection with the repayment, we incurred prepayment fees of $0.2 million which is included in loss on extinguishment of debt in the accompanying consolidated statements of operations. The loss on extinguishment of debt also includes the write-off of the unamortized debt premium of $0.2 million . On December 29, 2017, we repaid the $5.1 million outstanding balance on the 12907 Imperial Highway mortgage loan. We did not incur any prepayment penalties for repaying in advance of the maturity date of April 1, 2018. Credit Facility We have a $450.0 million senior unsecured credit facility (the “Credit Facility”), comprised of a $350.0 million unsecured revolving credit facility (the "Revolver") and a $100.0 million unsecured term loan facility (the "$100 Million Term Loan Facility"). The Revolver is scheduled to mature on February 12, 2021 , and has two six -month extension options available, and the $100 Million Term Loan Facility is scheduled to mature on February 14, 2022 . Under the terms of the Credit Facility, we may request additional lender commitments up to an additional aggregate $550.0 million , which may be comprised of additional revolving commitments under the Revolver, an increase to the $100 Million Term Loan Facility, additional term loan tranches or any combination of the foregoing. Interest on the Credit Facility, is generally to be paid based upon, at our option, either (i) LIBOR plus an applicable margin that is based upon our leverage ratio or (ii) the Base Rate (which is defined as the highest of (a) the federal funds rate plus 0.50% , (b) the administrative agent’s prime rate or (c) the Eurodollar Rate plus 1.00% ) plus an applicable margin that is based on our leverage ratio. The margins for the Revolver range in amount from 1.10% to 1.50% per annum for LIBOR-based loans and 0.10% to 0.50% per annum for Base Rate-based loans, depending on our leverage ratio. The margins for the $100 Million Term Loan Facility range in amount from 1.20% to 1.70% per annum for LIBOR-based loans and 0.20% to 0.70% per annum for Base Rate-based loans, depending on our leverage ratio. If we attain one additional investment grade rating by one or more of S&P or Moody’s to complement our current investment grade Fitch rating, we may elect to convert the pricing structure under the Credit Facility to be based on such rating. In that event, the margins for the Revolver will range in amount from 0.825% to 1.55% per annum for LIBOR-based loans and 0.00% to 0.55% per annum for Base Rate-based loans, depending on such rating, and the margins for the $100 Million Term Loan Facility will range in amount from 0.90% to 1.75% per annum for LIBOR-based loans and 0.00% to 0.75% per annum for Base Rate-based loans, depending on such rating. In addition to the interest payable on amounts outstanding under the Revolver, we are required to pay an applicable facility fee, based upon our leverage ratio, on each lender's commitment amount under the Revolver, regardless of usage. The applicable facility fee will range in amount from 0.15% to 0.30% per annum, depending on our leverage ratio. In the event that we convert the pricing structure to be based on an investment-grade rating, the applicable facility fee will range in amount from 0.125% to 0.30% per annum, depending on such rating. The Credit Facility is guaranteed by the Company and by substantially all of the current and to-be-formed subsidiaries of the Operating Partnership that own an unencumbered property. The Credit Facility is not secured by the Company’s properties or by equity interests in the subsidiaries that hold such properties. The Revolver and the $100 Million Term Loan Facility may be voluntarily prepaid in whole or in part at any time without premium or penalty. Amounts borrowed under the $100 Million Term Loan Facility and repaid or prepaid may not be reborrowed. The Credit Facility contains usual and customary events of default including defaults in the payment of principal, interest or fees, defaults in compliance with the covenants set forth in the Credit Facility and other loan documentation, cross-defaults to certain other indebtedness, and bankruptcy and other insolvency defaults. If an event of default occurs and is continuing under the Credit Facility, the unpaid principal amount of all outstanding loans, together with all accrued unpaid interest and other amounts owing in respect thereof, may be declared immediately due and payable. On December 31, 2018 , we did not have any borrowings outstanding under the Revolver, leaving $350.0 million available for additional borrowings. Debt Covenants The Credit Facility, the $225 Million Term Loan Facility, the $150 Million Term Loan Facility, the $100 million unsecured guaranteed senior notes (the “$100 Million Notes”), and the $125 Million Notes all include a series of financial and other covenants that we must comply with, including the following covenants which are tested on a quarterly basis: • Maintaining a ratio of total indebtedness to total asset value of not more than 60% ; • For the Credit Facility, the $225 Million Term Loan Facility and the $150 Million Term Loan Facility, maintaining a ratio of secured debt to total asset value of not more than 45% ; • For the $100 Million Notes and the $125 Million Notes, maintaining a ratio of secured debt to total asset value of not more than 40% ; • Maintaining a ratio of total secured recourse debt to total asset value of not more than 15% ; • Maintaining a minimum tangible net worth of at least the sum of (i) $760,740,750 , and (ii) an amount equal to at least 75% of the net equity proceeds received by the Company after September 30,2016; • Maintaining a ratio of adjusted EBITDA (as defined in each of the loan agreements) to fixed charges of at least 1.5 to 1.0; • Maintaining a ratio of total unsecured debt to total unencumbered asset value of not more than 60% ; and • Maintaining a ratio of unencumbered NOI (as defined in each of the loan agreements) to unsecured interest expense of at least 1.75 to 1.00. The Credit Facility, the $225 Million Term Loan Facility, the $150 Million Term Loan Facility, the $100 Million Notes and the $125 Million Notes also provide that our distributions may not exceed the greater of (i) 95.0% of our funds from operations or (ii) the amount required for us to qualify and maintain our status as a REIT and avoid the payment of federal or state income or excise tax in any 12-month period. Subject to the terms of the $100 Million Notes and the $125 Million Notes (together the “Notes”), upon certain events of default, including, but not limited to, (i) a default in the payment of any principal, make-whole payment amount, or interest under the Notes, (ii) a default in the payment of certain of our other indebtedness, (iii) a default in compliance with the covenants set forth in the Notes agreement, and (iv) bankruptcy and other insolvency defaults, the principal and accrued and unpaid interest and the make-whole payment amount on the outstanding Notes will become due and payable at the option of the purchasers. In addition, we are required to maintain at all times a credit rating on the Notes from either S&P, Moody’s or Fitch. In October 2018, Fitch upgraded the investment grade rating of the Notes to BBB from BBB- with a stable outlook. The $60 Million Term Loan contains the following financial covenants: • Maintaining a Debt Service Coverage Ratio (as defined in the term loan agreement) of at least 1.10 to 1.00, to be tested quarterly; • Maintaining Unencumbered Liquid Assets (as defined in the term loan agreement) of not less than (i) $5,000,000 , or (ii) $8,000,000 if we elect to have Line of Credit Availability (as defined in the term loan agreement) included in the calculation, of which $2,000,000 must be cash or cash equivalents, to be tested annually as of December 31 of each year; • Maintaining a minimum Fair Market Net Worth (as defined in the term loan agreement) of at least $75,000,000 , to be tested annually as of December 31 of each year. We were in compliance with all of our quarterly and annual debt covenants as of December 31, 2018 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Swaps	Interest Rate Swaps Risk Management Objective of Using Derivatives We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of our debt funding and the use of derivative financial instruments. Specifically, we enter into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are used to manage differences in the amount, timing, and duration of our known or expected cash payments principally related to our borrowings. Derivative Instruments Our objectives in using interest rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps involve the receipt of variable amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. We do not use derivatives for trading or speculative purposes. The effective portion of the change in fair value of derivatives designated and qualifying as cash flow hedges is initially recorded in accumulated other comprehensive income/(loss) (“AOCI”) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. On December 6, 2018, we entered into an interest rate swap transaction to manage our exposure to fluctuations in variable interest rate associated with the $150 Million Term Loan. The interest rate swap has a notional value of $150.0 million with an effective date of July 22, 2019, and a maturity date of November 22, 2024. Under the terms of the interest rate swap, we are required to make certain monthly fixed rate payments calculated on a notional value of $150 million , while the counterparty is obligated to make certain monthly floating rate payments based on LIBOR to us referencing the same notional value. The interest rate swap will effectively fix the annual interest rate payable on this notional value of the Company’s debt which may exist under the $150 Million Term Loan Facility at 2.7625% plus an applicable margin under the terms of the $150 Million Term Loan Facility. The following table sets forth a summary of our interest rate swaps at December 31, 2018 and December 31, 2017 (dollars in thousands): Current Notional Amount (2) Fair Value of Interest Rate Derivative Assets/(Derivative Liabilities) (2) Derivative Instrument Effective Date Maturity Date LIBOR Interest Strike Rate December 31, 2018 December 31, 2017 December 31, 2018 December 31, 2017 Interest Rate Swap 1/15/2015 2/15/2019 1.8260 % $ 30,000 $ 30,000 $ 25 $ (11 ) Interest Rate Swap 7/15/2015 2/15/2019 2.0100 % $ 28,108 $ 28,891 $ 17 $ (70 ) Interest Rate Swap 8/14/2015 12/14/2018 1.7900 % $ — $ 50,000 $ — $ (18 ) Interest Rate Swap 2/16/2016 12/14/2018 2.0050 % $ — $ 50,000 $ — $ (120 ) Interest Rate Swap 2/14/2018 1/14/2022 1.3490 % $ 125,000 $ — $ 3,974 $ 3,582 Interest Rate Swap 8/14/2018 1/14/2022 1.4060 % $ 100,000 $ — $ 3,023 $ 2,521 Interest Rate Swap 12/14/2018 8/14/2021 1.7640 % $ 100,000 $ — $ 1,731 $ 1,090 Interest Rate Swap 7/22/2019 11/22/2024 2.7625 % $ — $ — $ (2,351 ) $ — (1) Represents the notional value of swaps that are effective as of the balance sheet date presented.

Offsetting Derivatives We enter into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. Derivative instruments that are subject to master netting arrangements and qualify for net presentation in the consolidated balance sheets are presented on a gross basis in the consolidated balance sheets as of December 31, 2018 and December 31, 2017 .

Certain of our agreements with our derivative counterparties contain provisions where if a merger or acquisition occurs that materially changes our creditworthiness in an adverse manner, we may be required to fully collateralize our obligations under the derivative instrument.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We have adopted FASB Accounting Standards Codification Topic 820: Fair Value Measurements and Disclosure (“ASC 820”). ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances. ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Recurring Measurements – Interest Rate Swaps Currently, we use interest rate swap agreements to manage our interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. To comply with the provisions of ASC 820, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by ourselves and our counterparties. However, as of December 31, 2018 , we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, we have determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. The table below sets forth the estimated fair value of our interest rate swaps as of December 31, 2018 and 2017 , which we measure on a recurring basis by level within the fair value hierarchy (in thousands).

Fees and commissions earned from these entities are included in “Management, leasing and development services” in the consolidated statements of operations. We recorded $0.4 million , $0.4 million and $0.3 million during the years ended December 31, 2018 , 2017 and 2016 , respectively, in management, leasing and development services revenue. Purchase and Sale Agreement On November 30, 2017 , we entered into a purchase and sale agreement (the "Agreement") with 6110-6114 Cahuenga Avenue, LLC (the "Buyer"), which was subsequently amended on January 2, 2018, for the sale of our property located at 200-220 South Grand Avenue for a contract price of approximately $4.5 million .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal From time to time, we are party to various lawsuits, claims and legal proceedings that arise in the ordinary course of business. We are not currently a party to any legal proceedings that we believe would reasonably be expected to have a material adverse effect on our business, financial condition or results of operations. Environmental We generally will perform environmental site assessments at properties we are considering acquiring. After the acquisition of such properties, we continue to monitor the properties for the presence of hazardous or toxic substances. From time to time, we acquire properties with known adverse environmental conditions. If at the time of acquisition, losses associated with environmental remediation obligations are probable and can be reasonably estimated, we record a liability. On February 25, 2014, we acquired the property located at West 228th Street. Before purchasing the property, during the due diligence phase, we engaged a third party environmental consultant to perform various environmental site assessments to determine the presence of any environmental contaminants that might warrant remediation efforts. Based on their investigation, they determined that hazardous substances existed at the property and that additional assessment and remediation work would likely be required to satisfy regulatory requirements. The total remediation costs were estimated to be $1.3 million , which includes remediation, processing and oversight costs. To address the estimated costs associated with the environmental issues at the West 228th Street property, we entered into an Environmental Holdback Escrow Agreement (the “Holdback Agreement”) with the former owner, whereby $1.4 million was placed into an escrow account to be used to pay remediation costs. To fund the $1.4 million , the escrow holder withheld $1.3 million of the purchase price, which would have otherwise been paid to the seller at closing, and the Company funded an additional $0.1 million . According to the Holdback Agreement, the seller has no liability or responsibility to pay for remediation costs in excess of $1.3 million . As of December 31, 2018 and 2017 , we had a $1.0 million and $1.1 million contingent liability recorded in our consolidated balance sheets included in the line item “Accounts payable and accrued expenses,” reflecting the estimated remaining cost to remediate environmental liabilities at West 228th Street that existed prior to the acquisition date. As of December 31, 2018 and 2017 , we also had a $1.0 million and $1.1 million corresponding indemnification asset recorded in in our consolidated balance sheets in the line item “Other assets,” reflecting the estimated costs we expect the former owner to cover pursuant to the Holdback Agreement. We expect that the resolution of the environmental matters relating to the above will not have a material impact on our consolidated financial condition, results of operations or cash flows. However, we cannot be sure that we have identified all environmental liabilities at our properties, that all necessary remediation actions have been or will be undertaken at our properties or that we will be indemnified, in full or at all, in the event that such environmental liabilities arise. Furthermore, we cannot assure you that future changes to environmental laws or regulations and their application will not give rise to loss contingencies for future environmental remediation. Rent Expense As of December 31, 2018 , we lease a parcel of land that is currently being sub-leased to a tenant for a parking lot. This ground lease is scheduled to expire on June 1, 2062 . We recognized rental expense for our ground lease in the amount of $0.1 million , $0.1 million and $0.1 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. As part of conducting our day-to-day business, we also lease office space under operating leases. We recognized rental expense for our office space leases in the amount of $0.7 million , $0.5 million and $0.5 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. The future minimum commitment under our office space leases and ground lease as of December 31, 2018 , is as follows (in thousands): For the year ending December 31: Office Lease Ground Lease 2019 $ 668 $ 144 2020 257 144 2021 167 144 2022 — 144 2023 — 144 Thereafter — 5,532 Total $ 1,092 $ 6,252 On September 14, 2016 (the “Effective Date”), we entered into a ground lease for approximately 1.58 million square feet of land located in Corona, California, with the intention to develop buildings on the site. Under the terms of the ground lease, we had up to 420 days from the Effective Date, subject to certain conditions, to satisfy and waive certain contingencies, or terminate the ground leases for any reason. On March 13, 2017, we terminated the ground lease. As a result of the termination, we wrote-off $0.3 million of previously incurred transaction costs to the line item “Acquisition expenses” in the consolidated statements of operations. Tenant and Construction Related As of December 31, 2018 , we had commitments of approximately $25.5 million for tenant improvement and construction work under the terms of leases with certain of our tenants and contractual agreements with our construction vendors. Concentrations of Credit Risk We have deposited cash with financial institutions that are insured by the Federal Deposit Insurance Corporation up to $250,000 per institution. Although we have deposits at institutions in excess of federally insured limits as of December 31, 2018 , we do not believe we are exposed to significant credit risk due to the financial position of the institutions in which those deposits are held. As of December 31, 2018 , all of our properties are located in the Southern California infill markets. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory and social factors affecting the markets in which the tenants operate. During the year ended December 31, 2018 , no single tenant accounted for more than 5% of our total rental revenues.

Investment in Unconsolidated Real Estate	Investments in Unconsolidated Real Estate Entities On July 6, 2016, we acquired the property located at 3233 Mission Oaks Boulevard (the “final JV property”), which comprised substantially all of the JV’s assets, from the JV for a contract price of $25.7 million . Prior to the acquisition, our ownership interest in the final JV property was 15% . Following the acquisition, we own 100% of the final JV property and are accounting for it on a consolidated basis (See Note 3). In connection with the JV’s sale of the final JV property, we wrote-off the related $0.6 million unamortized basis adjustment. Immediately after the sale of the final JV property, the carrying value of our investment in unconsolidated real estate entities was $3.6 million . Following the sale of the final JV property, the JV distributed all of its available cash, with the exception of a small amount of working capital which was retained to cover any residual costs associated with the winding down of the JV. Our share of the JV distributions totaled $5.5 million , which exceeded the $3.6 million carrying value of our investment immediately after the sale of the final JV property. We recorded the $1.9 million of excess distributions as a realized gain in the line item “Equity in income from unconsolidated real estate entities” in the consolidated statements of operations. During the year ended December 31, 2017, the remaining assets were liquidated by the JV and we received a final distribution in the amount of $11 thousand which is reported in the line item “Equity in income from unconsolidated real estate entities” in the consolidated statements of operations. The following table presents the combined summarized results of operations of our unconsolidated joint venture. These amounts include the results of operations of the final JV property during the period prior to July 6, 2016, when we acquired the remaining 85% ownership interest in the final JV property.

Dividends on our Series A Preferred Stock and Series B Preferred Stock (collectively the “Series A and B Preferred Stock”) are cumulative from the date of original issuance and are payable quarterly in arrears on or about the last day of March, June, September and December of each year, beginning on December 31, 2016, for our Series A Preferred Stock and beginning on March 30, 2018, for our Series B Preferred Stock, at a rate of 5.875% per annum of its $25.00 per share liquidation preference (equivalent to $1.46875 per share per annum). The Series A and B Preferred Stock have no stated maturity date and are not subject to any mandatory redemption or sinking fund. The holders of our Series A and B Preferred Stock rank senior to the holders of our common stock with respect to dividend rights and rights upon the Company’s liquidation, dissolution or winding up of its affairs. The holders of our Series A and B Preferred Stock generally have no voting rights except for limited voting rights if we fail to pay dividends for six or more quarterly dividend periods (whether or not consecutive). We may not redeem the Series A Preferred Stock prior to August 16, 2021, and the Series B Preferred Stock prior to November 13, 2022, except in limited circumstances to preserve our status as a REIT or pursuant to a specified change of control transaction. On or after August 16, 2021, we may redeem our Series A Preferred Stock, and on or after November 13, 2022, we may redeem our Series B Preferred Stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus any accumulated, accrued and unpaid distributions through the date of redemption. Upon the occurrence of a specified change of control transaction, we may, at our option, redeem the Series A Preferred Stock and/or the Series B Preferred Stock in whole or in part within 120 days after the change of control occurred, by paying $25.00 per share in cash, plus any accrued and unpaid distributions through the date of redemption. If we do not exercise our right to redeem the Series A Preferred Stock and/or the Series B Preferred Stock, upon the occurrence of a specified change of control transaction, the holders of the Series A and B Preferred Stock have the right to convert some or all of their shares into a number of the Company’s common shares equivalent to $25.00 plus accrued and unpaid dividends, but not to exceed a cap of 2.2738 shares of common stock per share of Series A Preferred Stock or a cap of 1.6578 shares of common stock per share of Series B Preferred Stock, subject to certain adjustments. Common Stock Issuances On April 15, 2016, we completed a public follow-on offering of 10,350,000 shares of our common stock, including the underwriters’ exercise in full of its option to purchase 1,350,000 shares of our common stock, at an offering price of $17.65 per share. The net proceeds of the follow-on offering were $174.4 million , after deducting the underwriters’ discount and offering costs totaling $8.3 million . On April 15, 2016, we contributed the net proceeds of the offering to our Operating Partnership in exchange for 10,350,000 common units of partnership interests in the Operating Partnership (“OP Units”). ATM Program On June 13, 2018, we established a new at-the-market equity offering program (the “$400 Million ATM Program”) pursuant to which we may sell from time to time up to an aggregate of $400.0 million of our common stock through sales agents. The $400 Million ATM Program replaces our previous $300.0 million at-the-market equity offering program which was established on September 21, 2017. In addition, we previously established a $150 million at-the-market program on June 12, 2017, and a $125 million at-the-market program on April 17, 2015. All available shares of common stock under each of the $300 million, $150 million and $125 million at-the-market programs were sold prior to establishing new programs. During the year ended December 31, 2018 , we sold 18,177,242 shares of our common stock under our various at-the-market equity offering programs, at a weighted average price of $31.12 per share, for gross proceeds of $565.6 million , and net proceeds of 557.1 million , after deducting the sales agents’ fee. During the year ended December 31, 2017, we sold 11,968,927 shares of our common stock under our various at-the-market equity offering programs, at a weighted average price of $28.13 per share, for gross proceeds of $336.6 million , and net proceeds of $331.6 million , after deducting the sales agent’s fee. During the year ended December 31, 2016 , we sold 402,683 shares of our common stock under the $125 million at-the-market equity offering program, at a weighted average price of $23.13 per share, for gross proceeds of $9.3 million , and net proceeds of $9.2 million , after deducting the sales agents’ fee. As of December 31, 2018 , we had the capacity to issue up to an additional $63.4 million of common stock under the $400 Million ATM Program. Actual sales going forward, if any, will depend on a variety of factors, including among others, market conditions, the trading price of our common stock, determinations by us of the appropriate sources of funding for us and potential uses of funding available to us. Noncontrolling Interests Noncontrolling interests in our Operating Partnership relate to interests in the partnership that are not owned by us. As of December 31, 2018 , noncontrolling interests consisted of 1,838,565 OP Units and 577,246 fully-vested LTIP units and performance units which represented approximately 2.4% of our Operating Partnership. OP Units and shares of our common stock have essentially the same economic characteristics, as they share equally in the total net income or loss distributions of our Operating Partnership. Investors who own OP Units have the right to cause our Operating Partnership to redeem any or all of their units in our Operating Partnership for an amount of cash per unit equal to the then current market value of one share of common stock, or, at our election, shares of our common stock on a one-for-one basis. See Note 14 for a description of LTIP units and Performance Units. During the years ended December 31, 2018 , 2017 and 2016 , we redeemed 67,175 , 61,256 and 59,646 OP Units, respectively, in exchange for issuing to the holders of the OP Units an equal number of shares of our common stock, resulting in the reclassification of $0.6 million , $0.6 million , and $0.6 million , respectively, from noncontrolling interests to total stockholders’ equity. As described in Note 3, on April 15, 2016, as part of the REIT Portfolio Acquisition, we acquired 100% of the private REIT’s common stock and 575 of 700 issued and outstanding shares of the private REIT’s 12.5% cumulative non-voting preferred stock. The remaining 125 shares of preferred stock that were not immediately redeemed by us, were classified as noncontrolling interests in our consolidated balance sheets, with a balance equal to its liquidation preference of $1,000 per share, or an aggregate liquidation preference of $125,000 . On June 22, 2017, we adopted a plan of liquidation and dissolution of the private REIT, and on December 31, 2017 , we completed the liquidation of the private REIT, by distributing all assets to the Operating Partnership. As part of the liquidation process, we paid a liquidating distribution of $1,000 per share, or an aggregate liquidating distribution of $125,000 , as payment in full for the redemption of the remaining 125 shares of preferred stock not held by us. Changes in Accumulated Other Comprehensive Income (Loss) The following table summarizes the changes in our AOCI balance for the years ended December 31, 2018 and 2017 , which consists solely of adjustments related to our cash flow hedges: Years Ended December 31, 2018 2017 Accumulated other comprehensive income - beginning balance $ 6,799 $ 3,445 Other comprehensive income before reclassifications 649 2,084 Amounts reclassified from accumulated other comprehensive income to interest expense (1,204 ) 1,341 Net current period other comprehensive (loss) income (555 ) 3,425 Less: other comprehensive loss (income) attributable to noncontrolling interests 18 (71 ) Other comprehensive (loss) income attributable to common stockholders (537 ) 3,354 Accumulated other comprehensive income - ending balance $ 6,262 $ 6,799 Dividends Earnings and profits, which determine the taxability of dividends to stockholders, may differ from income reported for financial reporting purposes due to the differences for federal income tax purposes in the treatment of loss on extinguishment of debt, revenue recognition and compensation expense and in the basis of depreciable assets and estimated useful lives used to compute depreciation expense.

Incentive Award Plan

Incentive Award Plan	12 Months Ended
	Dec. 31, 2018
Equity [Abstract]
Incentive Award Plan	Incentive Award Plan Amended and Restated 2013 Incentive Award Plan On June 11, 2018, our stockholders approved the Amended and Restated Rexford Industrial Realty, Inc. and Rexford Industrial Realty, L.P. 2013 Incentive Award Plan (the “Plan”), superseding and replacing the Rexford Industrial Realty, Inc. and Rexford Industrial Realty, L.P. 2013 Incentive Award Plan (the “Prior Plan”). Pursuant to the Plan, we may continue to make grants of stock options, restricted stock, dividend equivalents, stock payments, restricted stock units, performance shares, LTIP units of partnership interest in our Operating Partnership (“LTIP units”), performance units in our Operating Partnership (“Performance Units”), and other stock based and cash awards to our non-employee directors, employees and consultants. The Plan is administered by our board of directors with respect to awards to non-employee directors and by our compensation committee with respect to other participants, each of which may delegate its duties and responsibilities to committees of our directors and/or officers (collectively the “plan administrator”), subject to certain limitations. The plan administrator sets the terms and conditions of all awards under the Plan, including any vesting and vesting acceleration conditions. The aggregate number of shares of our common stock, LTIP units and Performance Units that may be issued or transferred pursuant to the Plan is 1,770,000 plus any shares that have not been issued under the Prior Plan, including shares subject to outstanding awards under the Prior Plan that are not issued or delivered to a participant for any reason or that are forfeited by a participant prior to vesting. As of December 31, 2018 , a total of 1,832,380 shares of common stock, LTIP units and Performance Units remain available for issuance. Shares and units granted under the Plan may be authorized but unissued shares or units, or, if authorized by the board of directors, shares purchased in the open market. If an award under the Plan is forfeited, expires, or is settled for cash, any shares or units subject to such award will generally be available for future awards. LTIP Units and Performance Units LTIP units and Performance Units are each a class of limited partnership units in the Operating Partnership. Initially, LTIP units and Performance Units do not have full parity with OP Units with respect to liquidating distributions. However, upon the occurrence of certain events more fully described in the Operating Partnership’s partnership agreement (“book-up events”), the LTIP units and Performance Units can over time achieve full parity with the common units for all purposes. If such parity is reached, vested LTIP units and vested Performance Units may be converted into an equal number of OP Units, and, upon conversion, enjoy all rights of OP Units. LTIP units, whether vested or not, receive the same quarterly per-unit distributions as OP Units, which equal the per-share distributions on shares of our common stock. Performance Units that have not vested receive a quarterly per-unit distribution equal to 10% of the per-unit distribution paid on OP Units. On December 15, 2018 , the compensation committee awarded 132,875 LTIP units to Messrs. Howard Schwimmer, Michael S. Frankel, Adeel Khan and David Lanzer (collectively, the “executives”) that are subject to time-based vesting conditions (the “2018 LTIP Award”) and 204,517 Performance Units that are partially subject to market-based vesting conditions and partially subject to performance-based vesting conditions (the “2018 Performance Award”). In February 2018, the compensation committee chose to provide Messrs. Schwimmer and Frankel’s 2017 annual bonuses partly in cash and partly in LTIP units. Accordingly, on February 21, 2018, at the same time that annual bonuses were paid to the executives, Messrs. Schwimmer and Frankel were each granted 22,517 LTIP Units that were fully vested on the grant date. On December 15, 2017 , the compensation committee awarded 122,631 LTIP units to the executives that are subject to time-based vesting requirements (the “2017 LTIP Award”) and 188,250 Performance Units that are subject to market-based vesting conditions (the “2017 Market Performance Award”). On December 29, 2016 , the compensation committee awarded 116,690 LTIP units to the executives (not including Mr. Lanzer) that are subject to time-based vesting conditions (the “2016 LTIP Award”) and 199,000 Performance Units that are subject to market-based vesting conditions (the “2016 Market Performance Award”). 2018, 2017 and 2016 LTIP Unit Awards The 2018 LTIP Award and the 2017 LTIP Award are scheduled to vest one-third in equal installments on each of the first, second and third anniversaries of the grant date, and the 2016 LTIP Award is scheduled to vest in equal installments of 25% on each of the first, second, third and fourth anniversaries of the grant date. Each award is subject to each executive’s continued employment through the applicable vesting date, and subject to earlier vesting upon certain termination of employment or a change in control event, as described in the award agreements. Compensation expense will be recognized using the accelerated expense attribution method, with each vesting tranche valued as a separate award. The total grant date fair value of each annual LTIP award is based on the Company’s most recent closing stock price preceding the grant and the application of a discount for post-vesting restrictions and uncertainty regarding the occurrence and timing of book-up events. The following table summarizes these fair valuation assumptions and the grant date fair value of each annual LTIP award: 2018 LTIP Award 2017 LTIP Award 2016 LTIP Award Valuation date December 15, 2018 December 15, 2017 December 29, 2016 Closing share price of common stock $ 31.42 $ 30.58 $ 22.71 Discount for post-vesting restrictions and book-up events 7.7 % 5.0 % 5.0 % Grant date fair value (in thousands) $ 3,853 $ 3,563 $ 2,518 The following table sets forth our unvested LTIP Unit activity for the years ended December 31, 2018 , 2017 and 2016 : Number of Unvested LTIP Units Weighted-Average Grant Date Fair Value per Unit Balance at December 31, 2015 166,669 $ 15.11 Granted 116,690 $ 21.57 Vested (41,668 ) $ 13.91 Balance at December 31, 2016 241,691 $ 18.43 Granted 122,631 $ 29.05 Vested (70,837 ) $ 17.48 Balance at December 31, 2017 293,485 $ 23.10 Granted 190,318 $ 28.43 Vested (156,755 ) $ 23.29 Balance at December 31, 2018 327,048 $ 26.12 2018, 2017 and 2016 Performance Unit Award s Each of the 2018, 2017 and 2016 Performance Unit awards are comprised of a number of units designated as base units and a number of units designated as distribution equivalents, which are further described below: • Absolute TSR Base Units - base units that will vest based on varying levels of the Company’s total shareholder return (“TSR”) over the three -year performance period of an award. TSR is measured as the appreciation in the price per share of a company’s common stock plus dividends paid during the three -year performance period, assuming the reinvestment in common stock of all dividends paid during the performance period. • Relative TSR Base Units - base units that will vest based on the Company’s TSR as compared to the TSR percentage of a selected peer group of companies over the three -year performance period. • FFO Per-Share Base Units - base units that will vest based on the Company’s FFO per share growth over the three -year performance period. • Distribution Equivalent Units - Performance Units that have not vested will receive 10% of the distributions paid on OP units. The remaining 90% of the distributions will accrue (assuming the reinvestment in common stock of these distributions) during the three -year performance period and a portion will be paid out as distribution equivalent units based upon the number of base units that ultimately vest. For the 2018 Performance Award, one-third of the base units are designated as Absolute TSR Base Units and one-third of the base units are designated as Relative TSR Base Units (combined, the “2018 Market Performance Award”). The remaining one-third of the base units are designated as FFO Per-Share Base Units (the “2018 FFO Per-Share Award”). For each of the 2017 Market Performance Award and the 2016 Market Performance Award, 40% of the base units are designated as Absolute TSR Base Units and the other 60% are designated as Relative TSR Base Units. The following table summarizes the performance levels and vesting percentages for the Absolute TSR Base Units, Relative TSR Base Units and FFO Per-Share Base Units, and the three-year performance period for each of the Performance Unit awards: Absolute TSR Base Units Relative TSR Base Units FFO Per-Share Base Units Performance Level Company TSR Percentage Absolute TSR Vesting Percentage Peer Group Relative Performance Relative TSR Vesting Percentage FFO per Share Growth FFO Vesting Percentage Three-Year Performance Period 2018 Award < 18% — % < 35th Percentile — % < 12% — % “Threshold Level” 18 % 25 % 35th Percentile 25 % 12 % 25 % Jan 1, 2019 “Target Level” 24 % 60 % 55th Percentile 60 % 16.5 % 60 % to “Maximum Level” ≥ 30% 100 % ≥ 75th Percentile 100 % ≥ 21% 100 % Dec 31, 2021 2017 Award < 18% — % < 35th Percentile — % -- -- “Threshold Level” 18 % 25 % 35th Percentile 25 % -- -- Dec 15, 2017 “Target Level” 27 % 60 % 55th Percentile 60 % -- -- to “Maximum Level” ≥ 36% 100 % ≥ 75th Percentile 100 % -- -- Dec 14, 2020 2016 Award < 21% — % < 50th Percentile — % -- -- “Threshold Level” 21 % 25 % 50th Percentile 25 % -- -- Dec 29, 2016 “Target Level” 35.5 % 60 % 62.5th Percentile 60 % -- -- to “Maximum Level” ≥ 50% 100 % ≥ 75th Percentile 100 % -- -- Dec 28, 2019 If the Company’s TSR percentage, peer group relative performance or FFO per share growth falls between the levels specified in the tables above, the percentage of Absolute TSR Base Units, Relative TSR Base Units and FFO Per-Share Base Units that vest will be determined using straight-line interpolation between such levels. Fair Value of Awards With Market-Based Vesting Conditions The grant date fair value of each of the 2018, 2017 and 2016 Market Performance Awards is based on the sum of the following: (1) the present value of the expected payoff to the vested absolute and relative base units, (2) the present value of the 10% portion of the distribution expected to be paid during the three-year performance period, and (3) the present value of the distribution equivalent units expected to be awarded at the end of the three-year performance period. The grant date fair value of each of these awards was measured using a Monte Carlo simulation pricing model, which uses 100,000 trial simulations, to estimate the probability that the market conditions, TSR on both an absolute and relative basis, will be achieved over the three-year performance period. The following table summarizes the assumptions we used in the Monte Carlo simulations and the grant date fair value of the awards with market-based vesting conditions. 2018 Market Performance Award 2017 Market Performance Award 2016 Market Performance Award Valuation date December 15, 2018 December 15, 2017 December 29, 2016 Expected share price volatility for the Company 20.0 % 18.0 % 20.0 % Expected share price volatility for peer group companies - low end of range (1) 16.0 % 15.0 % 21.0 % Expected share price volatility for peer group companies - high end of range (1) 100.0 % 100.0 % 50.0 % Expected dividend yield 2.50 % 2.40 % 2.80 % Risk-free interest rate 2.80 % 1.96 % 1.49 % Grant date fair value (in thousands) $ 2,090 $ 2,714 $ 1,753 (1) For the 2018 Market Performance Award, the median and average expected share price volatilities for the peer group companies are 23.0% and 27.1% , respectively. For the 2017 Market Performance Award, the median and average expected share price volatilities for the peer group companies are 21.0% and 25.3% , respectively. The expected share price volatilities are based on a mix of the historical and implied volatilities of the Company and the peer group companies. The expected dividend yield is based on our average historical dividend yield since our IPO and our dividend yield as of the valuation date for each award. The risk-free interest rate is based on U.S. Treasury note yields matching the three-year time period of the performance period. Compensation cost for the awards with market-based vesting conditions will be recognized ratably over the requisite service period, regardless of whether the TSR performance levels are achieved and any awards ultimately vest. Compensation expense will only be reversed if the holder of an award with market-based vesting conditions forfeits the award by leaving the employment of the Company prior to vesting. Fair Value of Awards with Performance-Based Vesting Conditions The grant date fair value of the 2018 FFO Per-Share Award is based on the Company’s most recent closing stock price preceding the grant date ( $31.42 on December 14, 2018). The grant date fair value and maximum potential expense if the maximum performance level were met for this award is $2.0 million . Compensation cost for the 2018 FFO Per-Share Award will reflect the number of units that are expected to vest based on the probable outcome of the performance condition and will be adjusted to reflect those units that ultimately vest at the end of the three-year performance period. 2015 Performance Award Vesting On December 14, 2018, the three -year performance period for the 2015 performance award ended, and the following Performance Units vested: (i) 100% of the 115,600 Absolute TSR Base Units based on the Company achieving a TSR greater than 50%, the maximum level, (ii) 100% of the 173,399 Relative TSR Base Units based on the Company finishing in the 75th or greater percentile, the maximum level, of the peer group of companies included in the SNL U.S. Equity REIT Index (with respect to entities with an implied market capitalization of $500 million to $1 billion), and (iii) 18,987 distribution equivalents, for a total of 307,986 vested Performance Units. On December 14, 2018, we canceled the remaining 8,012 distribution equivalents that did not vest. Restricted Common Stock Shares of our restricted common stock generally may not be sold, pledged, assigned or transferred in any manner other than by will or the laws of descent and distribution or, subject to the consent or the administrator of the Plan, a domestic relations order, unless and until all restrictions applicable to such shares have lapsed. Such restrictions generally expire upon vesting. Shares of our restricted common stock are participating securities and have full voting rights and nonforfeitable rights to dividends. The compensation committee has periodically awarded grants of restricted common stock to various employees of the Company, other than executives, for the purpose of attracting or retaining the services of these key individuals. These grants typically vest in four equal, annual installments on each of the first four anniversaries of the date of grant, subject to the employee’s continued service. During the year ended December 31, 2018 , we granted 90,754 shares of restricted common stock to non-executive employees. The grant date fair value of these awards was $2.5 million based on the closing share price of the Company’s common stock on the date of grant, which ranged from $27.20 to $31.29 per share. In accordance with the Rexford Industrial Realty, Inc. Non-Employee Director Compensation Program, each year on the date of the annual meeting of the Company’s stockholders, we grant shares of restricted common stock to each of our non-employee directors who are re-elected for another year of service. These awards vest on the earlier of (i) the date of the annual meeting of the Company’s stockholders next following the grant date and (ii) the first anniversary of the grant date, subject to each non-employee director’s continued service. During the year ended December 31, 2018 , we granted 2,268 shares of restricted common stock to each of our six non-employee directors. The grant date fair value of each award was $70,000 based on the $30.86 closing share price of the Company’s common stock on the date of grant. The following table sets forth our unvested restricted stock activity for the years ended December 31, 2018 , 2017 and 2016 : Number of Unvested Shares of Restricted Common Stock Weighted-Average Grant Date Fair Value per Share Balance at December 31, 2015 333,441 $ 14.30 Granted 103,704 $ 18.03 Forfeited (23,968 ) $ 15.37 Vested (1)(2) (125,350 ) $ 14.63 Balance at December 31, 2016 287,827 $ 15.92 Granted 104,727 $ 23.78 Forfeited (35,959 ) $ 18.74 Vested (1)(2) (165,900 ) $ 15.43 Balance at December 31, 2017 190,695 $ 20.13 Granted 104,560 $ 27.72 Forfeited (13,031 ) $ 23.51 Vested (1)(2) (81,826 ) $ 19.40 Balance at December 31, 2018 200,398 $ 24.17 (1) The total fair value of vested shares, which is calculated as the number of shares vested multiplied by the closing share price of the Company’s common stock on the vesting date, was $2.4 million , $4.5 million and $2.6 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. (2) Total shares vested include 21,324 , 57,444 and 36,374 shares of common stock that were tendered by employees during the years ended December 31, 2018 , 2017 and 2016 , respectively, to satisfy minimum statutory tax withholding requirements associated with the vesting of restricted shares. Compensation Expense The following table sets forth the amounts expensed and capitalized for all share-based awards for the reported periods presented below (in thousands): Year Ended December 31, 2018 2017 2016 Expensed share-based compensation (1) $ 10,147 $ 5,398 $ 3,835 Capitalized share-based compensation (2) 255 162 147 Total share-based compensation $ 10,402 $ 5,560 $ 3,982 (1) Amounts expensed are included in “General and administrative” and “Property expenses” in the accompanying consolidated statements of operations. (2) Amounts capitalized, which relate to employees who provide construction and leasing services, are included in “Building and improvements” and “Deferred leasing costs, net” in the accompanying consolidated balance sheets. Compensation expense for the year ended December 31, 2018 , includes $1.2 million for the 45,034 immediately vested LTIP units that were granted on February 21, 2018 to satisfy a portion of Messrs. Schwimmer and Frankel’s bonuses that were accrued during the year ended December 31, 2017. In May 2018, the compensation committee designated to have payouts for Messrs.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The following table sets forth the computation of basic and diluted earnings per share (in thousands, except share and per share amounts): Year Ended December 31, 2018 2017 2016 Numerator: Net income $ 47,075 $ 41,700 $ 25,876 Less: Preferred stock dividends (9,694 ) (5,875 ) (1,983 ) Less: Net income attributable to noncontrolling interests (865 ) (988 ) (750 ) Less: Net income attributable to participating securities (378 ) (410 ) (302 ) Net income attributable to common stockholders $ 36,138 $ 34,427 $ 22,841 Denominator: Weighted average shares of common stock outstanding - basic 86,824,235 71,198,862 62,723,021 Effect of dilutive securities - performance units 511,514 399,792 242,533 Weighted average shares of common stock outstanding - diluted 87,335,749 71,598,654 62,965,554 Earnings per share - Basic Net income attributable to common stockholders $ 0.42 $ 0.48 $ 0.36 Earnings per share - Diluted: Net income attributable to common stockholders $ 0.41 $ 0.48 $ 0.36 Unvested share-based payment awards that contain non-forfeitable rights to dividends, whether paid or unpaid, are accounted for as participating securities. As such, unvested shares of restricted stock, unvested LTIP Units and unvested Performance Units are considered participating securities. Participating securities are included in the computation of basic EPS pursuant to the two-class method. The two-class method determines EPS for each class of common stock and each participating security according to dividends declared (or accumulated) and their respective participation rights in undistributed earnings. Participating securities are also included in the computation of diluted EPS using the more dilutive of the two-class method or treasury stock method for unvested shares of restricted stock and LTIP Units, and by determining if certain market conditions have been met at the reporting date for unvested Performance Units. The effect of including unvested shares of restricted stock and unvested LTIP Units using the treasury stock method was excluded from our calculation of weighted average shares of common stock outstanding – diluted, as their inclusion would have been anti-dilutive. Performance Units, which are subject to vesting based on the Company achieving certain TSR levels over a three -year performance period, are included as contingently issuable shares in the calculation of diluted EPS when TSR has been achieved at or above the threshold levels specified in the award agreements, assuming the reporting period is the end of the performance period, and the effect is dilutive. We also consider the effect of other potentially dilutive securities, including OP Units, which may be redeemed for shares of our common stock under certain circumstances, and include them in our computation of diluted EPS when their inclusion is dilutive.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Consolidation	Basis of Presentation and Principles of Consolidation The accompanying financial statements are the consolidated financial statements of Rexford Industrial Realty, Inc. and its subsidiaries, including our Operating Partnership. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements. Under consolidation guidance, we have determined that our Operating Partnership is a variable interest entity because the holders of limited partnership interests do not have substantive kick-out rights or participating rights. Furthermore, we are the primary beneficiary of the Operating Partnership because we have the obligation to absorb losses and the right to receive benefits from the Operating Partnership and the exclusive power to direct the activities of the Operating Partnership. As of December 31, 2018 and 2017 , the assets and liabilities of the Company and the Operating Partnership are substantially the same, as the Company does not have any significant assets other than its investment in the Operating Partnership.
Basis of Accounting	The accompanying consolidated financial statements have been prepared in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) as established by the Financial Accounting Standards Board (“FASB”) in the Accounting Standards Codification including modifications issued under Accounting Standards Updates (“ASUs”). Any reference to the number of properties, buildings and square footage are unaudited and outside the scope of our independent auditor’s audit of our financial statements in accordance with the standards of the Public Company Accounting Oversight Board.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents Cash and cash equivalents include all cash and liquid investments with an initial maturity of three months or less. The carrying amount approximates fair value due to the short-term maturity of these investments. Restricted Cash Restricted cash is generally comprised of cash proceeds related to property dispositions that are being held by qualified intermediaries for purposes of facilitating tax-deferred like-kind exchanges under Section 1031 of the Internal Revenue Code (“1031 Exchange”).
Investment in Real Estate	Investment in Real Estate Acquisitions Effective January 1, 2017, we adopted Accounting Standards Update (“ASU”) 2017-01, Business Combinations - Clarifying the Definition of a Business (“ASU 2017-01’), which provides a new framework for determining whether transactions should be accounted for as acquisitions of assets or businesses. Under ASU 2017-01, when substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single identifiable asset or a group of similar assets, the set of assets and activities is not a business. ASU 2017-01 also revises the definition of a business to include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create an output. We evaluated the acquisitions that we completed during the years ended December 31, 2018 and 2017 , and determined that under this framework these transactions should be accounted for as asset acquisitions. We expect that most of our property acquisitions will generally not meet the revised definition of a business because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets or because the acquisition does not include a substantive process. For acquisitions that are accounted for as asset acquisitions, because they do not meet the business combination accounting criteria, we allocate the cost of the acquisition, which includes the purchase price and associated acquisition transaction costs, to the individual assets acquired and liabilities assumed on a relative fair value basis. These individual assets and liabilities typically include land, building and improvements, tenant improvements, intangible assets and liabilities related to above and below market leases, intangible assets related to in-place leases, and from time to time, assumed debt. As there is no measurement period concept for an asset acquisition, the allocated cost of the acquired assets is finalized in the period in which the acquisition occurs. We determine the fair value of the tangible assets of an acquired property by valuing the property as if it were vacant. This “as-if vacant” value is estimated using an income, or discounted cash flow, approach that relies upon Level 3 inputs, which are unobservable inputs based on the Company’s assumptions about the assumptions a market participant would use. These Level 3 inputs include discount rates, capitalization rates, market rents and comparable sales data for similar properties. Estimates of future cash flows are based on a number of factors including historical operating results, known and anticipated trends, and market and economic conditions. In calculating the “as-if-vacant” value for acquisitions completed during the year ended December 31, 2018 , we used discount rates ranging from 5.50% to 7.50% and capitalization rates ranging from 4.25% to 6.25% . In determining the fair value of intangible lease assets or liabilities, we also consider Level 3 inputs. Acquired above- and below-market leases are valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the term of any below-market fixed rate renewal options for below-market leases, if applicable. The estimated fair value of acquired in-place at-market tenant leases are the costs that would have been incurred to lease the property to the occupancy level of the property at the date of acquisition. Such estimates include the value associated with leasing commissions, legal and other costs, as well as the estimated period necessary to lease such property to its occupancy level at the time of its acquisition. In determining the fair value of acquisitions completed during the year ended December 31, 2018 , we used an estimated average lease-up period ranging from six to twelve months. The difference between the fair value and the face value of debt assumed in connection with an acquisition is recorded as a premium or discount and amortized to “interest expense” over the life of the debt assumed. The valuation of assumed liabilities is based on our estimate of the current market rates for similar liabilities in effect at the acquisition date. Capitalization of Costs We capitalize direct costs incurred in developing, renovating, rehabilitating and improving real estate assets as part of the investment basis. This includes certain general and administrative costs, including payroll, bonus, and noncash equity compensation of the personnel performing development, renovations and rehabilitation if such costs are identifiable to a specific activity to get the real estate asset ready for its intended use. During the development and construction periods of a project, we also capitalize interest, real estate taxes and insurance costs. We cease capitalization of costs upon substantial completion of the project, but no later than one year from cessation of major construction activity. If some portions of a project are substantially complete and ready for use and other portions have not yet reached that stage, we cease capitalizing costs on the completed portion of the project but continue to capitalize for the incomplete portion of the project. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. We capitalized interest costs of $2.1 million , $1.7 million and $1.7 million during the years ended December 31, 2018 , 2017 and 2016 , respectively. We capitalized real estate taxes and insurance aggregating $0.9 million , $1.2 million , and $0.8 million and during the years ended December 31, 2018 , 2017 and 2016 , respectively. We capitalized compensation costs for employees who provide construction services of $2.2 million , $1.9 million and $1.0 million during the years ended December 31, 2018 , 2017 and 2016 , respectively. Depreciation and Amortization Real estate, including land, building and land improvements, tenant improvements, furniture, fixtures and equipment and intangible lease assets and liabilities are stated at historical cost less accumulated depreciation and amortization, unless circumstances indicate that the cost cannot be recovered, in which case, the carrying value of the property is reduced to estimated fair value as discussed below in our policy with regard to impairment of long-lived assets. We estimate the depreciable portion of our real estate assets and related useful lives in order to record depreciation expense. The values allocated to buildings, site improvements, in-place lease intangibles and tenant improvements are depreciated on a straight-line basis using an estimated remaining life of 10 - 30 years for buildings, 5 - 20 years for site improvements, and the shorter of the estimated useful life or respective lease term for in-place lease intangibles and tenant improvements. As discussed above in— Investments In Real Estate — Acquisitions , in connection with property acquisitions, we may acquire leases with rental rates above or below the market rental rates. Such differences are recorded as an acquired lease intangible asset or liability and amortized to “rental revenues” over the remaining term of the related leases. Our estimate of the useful life of our assets is evaluated upon acquisition and when circumstances indicate a change in the useful life, which requires significant judgment regarding the economic obsolescence of tangible and intangible assets.
Assets Held for Sale	Assets Held for Sale We classify a property as held for sale when all of the criteria set forth in ASC Topic 360: Property, Plant and Equipment (“ASC 360”) have been met. The criteria are as follows: (i) management, having the authority to approve the action, commits to a plan to sell the property; (ii) the property is available for immediate sale in its present condition, subject only to terms that are usual and customary; (iii) an active program to locate a buyer and other actions required to complete the plan to sell have been initiated; (iv) the sale of the property is probable and is expected to be completed within one year; (v) the property is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (vi) actions necessary to complete the plan of sale indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. At the time we classify a property as held for sale, we cease recording depreciation and amortization. A property classified as held for sale is measured and reported at the lower of its carrying amount or its estimated fair value less cost to sell. See Note 12.
Deferred Leasing Costs	Deferred Leasing Costs We capitalize costs directly related to the successful origination of a lease. These costs include leasing commissions paid to third parties for new leases or lease renewals, as well as an allocation of compensation costs, including payroll, bonus and non-cash equity compensation, of employees who spend time on lease origination activities. In determining the amount of compensation costs to be capitalized for these employees, allocations are made based on estimates of the actual amount of time spent working on successful leases in comparison to time spent on unsuccessful origination efforts.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets In accordance with the provisions of the Impairment or Disposal of Long-Lived Assets Subsections of ASC 360, we assess the carrying values of our respective long-lived assets, including goodwill, whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Recoverability of real estate assets is measured by comparison of the carrying amount of the asset to the estimated future undiscounted cash flows. To review real estate assets for recoverability, we consider current market conditions as well as our intent with respect to holding or disposing of the asset. The intent with regard to the underlying assets might change as market conditions and other factors change. Fair value is determined through various valuation techniques, including discounted cash flow models, applying a capitalization rate to estimated net operating income of a property, quoted market values and third party appraisals, where considered necessary. The use of projected future cash flows is based on assumptions that are consistent with estimates of future expectations and the strategic plan used to manage our underlying business. If our analysis indicates that the carrying value of the real estate asset is not recoverable on an undiscounted cash flow basis, we will recognize an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the real estate property. Assumptions and estimates used in the recoverability analyses for future cash flows, discount rates and capitalization rates are complex and subjective. Changes in economic and operating conditions or our intent with respect to our investment that occur subsequent to our impairment analyses could impact these assumptions and result in future impairment of our real estate properties.
Investment in Unconsolidated Real Estate	Investment in Unconsolidated Real Estate Entities Investments in unconsolidated real estate entities in which we have the ability to exercise significant influence (but not control) are accounted for under the equity method of investment. Under the equity method, we initially record our investment at cost, and subsequently adjust for equity in earnings or losses and cash contributions and distributions. Any difference between the carrying amount of these investments on the balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in income (loss) from unconsolidated real estate over the life of the related asset. Under the equity method of accounting, our net equity investment is reflected within the consolidated balance sheets, and our share of net income or loss from the joint ventures is included within the consolidated statements of operations. Furthermore, distributions received from equity method investments are classified as either operating cash inflows or investing cash inflows in the consolidated statements of cash flows using the “nature of the distribution approach,” in which each distribution is evaluated on the basis of the source of the payment. See Note 11.
Income Taxes	Income Taxes We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) commencing with our initial taxable year ended December 31, 2013. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the Code relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and were unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax. In addition, we are subject to taxation by various state and local jurisdictions, including those in which we transact business or reside. Our non-taxable REIT subsidiaries, including our Operating Partnership, are either partnerships or disregarded entities for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities and flow-through entities such as partnerships is reportable in the income tax returns of the respective equity holders. Accordingly, no income tax provision is included in the accompanying consolidated financial statements for the years ended December 31, 2018 , 2017 and 2016 . We periodically evaluate our tax positions to determine whether it is more likely than not that such positions would be sustained upon examination by a tax authority for all open tax years, as defined by the statute of limitations, based on their technical merits. As of December 31, 2018 and 2017 , we have not established a liability for uncertain tax positions.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities ASC Topic 815: Derivatives and Hedging (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. As required by ASC 815, we record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, and whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. We may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting does not apply or we elect not to apply hedge accounting. See Note 7.
Revenue Recognition	Revenue Recognition Our primary sources of revenue are rental income, tenant reimbursements, other income, management, leasing and development services and gains on sale of real estate. Rental Income Minimum annual rental revenues are recognized in rental income on a straight-line basis over the term of the related lease, regardless of when payments are contractually due. Rental revenue recognition commences when the tenant takes possession or controls the physical use of the leased space. Lease termination fees, which are included in rental income, are amortized over the remaining term of the lease until we have no continuing obligation to provide services to such former tenant. Tenant Reimbursements Our lease agreements with tenants generally contain provisions that require tenants to reimburse us for certain property expenses. Estimated reimbursements from tenants for real estate taxes, common area maintenance and other recoverable operating expenses are recognized as revenues in the period that the expenses are incurred. Subsequent to year-end, we perform final reconciliations on a lease-by-lease basis and bill or credit each tenant for any cumulative annual adjustments. Other Income Other income primarily consists of late payment fees and other miscellaneous tenant related revenues. Management, leasing and development services We provide property management services and leasing services to related party and third-party property owners, the customer, in exchange for fees and commissions. Property management services include performing property inspections, monitoring repairs and maintenance, negotiating vendor contracts, maintaining tenant relations and providing financial and accounting oversight. For these services, we earn monthly management fees, which are based on a fixed percentage of each managed property’s monthly tenant cash receipts. We have determined that control over the services is passed to the customer simultaneously as performance occurs. Accordingly, management fee revenue is earned as the services are provided to our customers. Leasing commissions are earned when we provide leasing services that result in an executed lease with a tenant. We have determined that control over the services is transferred to the customer upon execution of each lease agreement. We earn leasing commissions based on a fixed percentage of rental income generated for each executed lease agreement and there is no variable income component. Gain or Loss on Sale of Real Estate We account for dispositions of real estate properties, which are considered nonfinancial assets, in accordance with ASC 610-20: Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets and recognize a gain or loss on sale of real estate upon transferring control of the nonfinancial asset to the purchaser, which is generally satisfied at the time of sale. If we were to conduct a partial sale of real estate by transferring a controlling interest in a nonfinancial asset, while retaining a noncontrolling ownership interest, we would measure any noncontrolling interest received or retained at fair value, and recognize a full gain or loss. If we receive consideration before transferring control of a nonfinancial asset, we recognize a contract liability. If we transfer control of the asset before consideration is received, we recognize a contract asset.
Valuation of Receivables	Valuation of Receivables We may be subject to tenant defaults and bankruptcies that could affect the collection of outstanding receivables. In order to mitigate these risks, we perform credit reviews and analyses on prospective tenants before significant leases are executed and on existing tenants before properties are acquired. We specifically analyze aged receivables, customer credit-worthiness, historical bad debts and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. As a result of our periodic analysis, we maintain an allowance for estimated losses that may result from the inability of our tenants to make required payments. This estimate requires significant judgment related to the lessees’ ability to fulfill their obligations under the leases. We believe our allowance for doubtful accounts is adequate for our outstanding receivables for the periods presented. If a tenant is insolvent or files for bankruptcy protection and fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the net outstanding balances, which include amounts recognized as straight-line revenue not realizable until future periods.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs related to a recognized debt liability are presented in the balance sheet as a reduction from the carrying value of the debt liability. This offset against the debt liability is treated similarly to a debt discount, which effectively reduces the proceeds of a borrowing. For line of credit arrangements, we present debt issuance costs as an asset and amortize the cost over the term of the line of credit arrangement. See Note 5.
Equity Based Compensation	Equity Based Compensation We account for equity based compensation in accordance with ASC Topic 718 Compensation – Stock Compensation . Total compensation cost for all share-based awards is based on the estimated fair market value on the grant date. For share-based awards that vest based solely on a service condition, we recognize compensation cost on a straight-line basis over the total requisite service period for the entire award. For share-based awards that vest based on a market condition, we recognize compensation cost on a straight-line basis over the requisite service period of each separately vesting tranche. For share-based awards that vest based on a performance condition, we recognize compensation cost based on the number of awards that are expected to vest based on the probable outcome of the performance condition. Compensation cost for these awards will be adjusted to reflect the number of awards that ultimately vest. Forfeitures are recognized in the period in which they occur. See Note 14.
Equity Offering Costs	Equity Offering Costs Underwriting commissions and offering costs related to our common stock issuances have been reflected as a reduction of additional paid-in capital. Underwriting commissions and offering costs related to our preferred stock issuances have been reflected as a direct reduction of the preferred stock balance.
Earnings Per Share	Earnings Per Share We calculate earnings per share (“EPS”) in accordance with ASC 260 – Earnings Per Share (“ASC 260”). Under ASC 260, nonvested share-based payment awards that contain non-forfeitable rights to dividends are participating securities and, therefore, are included in computing basic EPS pursuant to the two-class method. The two-class method determines EPS for each class of common stock and participating securities according to dividends declared (or accumulated) and their respective participation rights in undistributed earnings. Basic EPS is calculated by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted EPS is calculated by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding determined for the basic EPS computation plus the effect of any dilutive securities. We include unvested shares of restricted stock and unvested LTIP units in the computation of diluted EPS by using the more dilutive of the two-class method or treasury stock method. We include unvested performance units as contingently issuable shares in the computation of diluted EPS once the market criteria are met, assuming that the end of the reporting period is the end of the contingency period. Any anti-dilutive securities are excluded from the diluted EPS calculation. See Note 15.
Segment Reporting	Segment Reporting Management views the Company as a single segment based on its method of internal reporting in addition to its allocation of capital and resources.
Recently Issued Accounting Pronouncements	Adoption of New Accounting Pronouncements Revenue Recognition (ASC 606) On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), and subsequently issued additional ASUs which provide practical expedients, technical corrections and clarification of the new standard (collectively “ASC 606”). ASC 606 establishes principles for reporting the nature, amount, timing and uncertainty of revenues and cash flows arising from an entity’s contracts with customers. The core principle of the new standard is that an entity recognizes revenue to represent the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Effective January 1, 2018, we adopted ASC 606 using the modified retrospective approach. We evaluated each of our revenue streams to determine the sources of revenue that are impacted by ASC 606 and concluded that management services and leasing services fall within the scope of ASC 606. We evaluated the impact of ASC 606 on the timing and pattern of revenue recognition for our management and leasing services contracts and determined there was no change in the timing or pattern of revenue recognition for these contracts as compared to prior accounting practice. Accordingly, the adoption of ASC 606 did not have an impact on our consolidated financial statements. See “Revenue Recognition” above for further details. Derecognition of Non-Financial Assets On February 22, 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05). ASU 2017-05 clarifies the scope of asset derecognition and adds further guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with non-customers. Effective January 1, 2018, we adopted ASU 2017-05 using the modified retrospective approach. There was no cumulative effect adjustment recorded to retained earnings as of January 1, 2018 as a result of the adoption of ASU 2017-05. Derivatives On August 28, 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). ASU 2017-12 simplifies hedge accounting by eliminating the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. For cash flow hedges, ASU 2017-12 requires all changes in the fair value of the hedging instrument to be deferred in other comprehensive income and recognized in earnings at the same time that the hedged item affects earnings. ASU 2017-12 also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. ASU 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. Effective January 1, 2018, we early adopted ASU 2017-12 using the modified retrospective approach. We did not record a cumulative effect adjustment to eliminate ineffectiveness amounts as we did not have any ineffectiveness in our historical consolidated financial statements. In addition, certain provisions of ASU 2017-12 require modifications to existing presentation and disclosure requirements on a prospective basis. See Note 7 for disclosures relating to our derivative instruments. Stock Compensation On May 10, 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”), which clarifies the scope of modification accounting for share-based compensation arrangements by providing guidance on the types of changes to the terms and conditions of share-based compensation awards to which an entity would be required to apply modification accounting under ASC 718. ASU 2017-09 is effective for annual periods beginning after December 15, 2017, with early adoption permitted. Effective January 1, 2018, we adopted ASU 2017-09. There was no change to our consolidated financial statements or notes to our consolidated financial statements as a result of the adoption of ASU 2017-09. Recently Issued Accounting Pronouncements Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. We consider the applicability and impact of all ASUs. Leases On February 25, 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which sets out the principals for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. ASU 2016-02 was subsequently amended by the following updates: (i) ASU 2018-10, Leases: Codification Improvements to Topic 842, (ii) ASU 2018-11, Leases: Targeted Improvements and (iii) ASU 2018-20, Leases: Narrow-Scope Improvements for Lessors (collectively referred to as “ASC 842”). ASC 842 is effective for annual periods beginning after December 15, 2018, which for us is January 1, 2019, and early adoption is permitted. The transition provisions of ASC 842 are required to be applied using a modified retrospective approach, however, an entity can choose to apply the provisions either at the beginning of the earliest comparative period presented in the consolidated financial statements or at the beginning of the period of adoption (the “effective date method”). Under the effective date method, an entity would continue to apply the legacy lease guidance in current GAAP (“ASC 840”), including its disclosure requirements, in the comparative periods presented in the financial statements. Under either transition method, ASC 842 includes the following practical expedients that can be elected by an entity to be applied to all leases that commence before the effective date: (i) the “package of practical expedients” which allows an entity to not reassess (a) whether expired or existing contracts contain leases, (b) lease classification for expired or existing leases and (c) whether previously capitalized initial direct costs would qualify for capitalization under ASC 842 and (ii) the “use of hindsight practical expedient”. On January 1, 2019, we adopted ASC 842 using the effective date method and elected the package of practical expedients. We did not elect the use of hindsight practical expedient. ASC 842 requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASC 842 also requires lessees to classify leases as either finance or operating leases based on whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification is used to evaluate whether the lease expense should be recognized based on an effective interest method or on a straight-line basis over the term of the lease. As of December 31, 2018 , we are the lessee on one ground lease and multiple office space leases, which are classified as operating leases under ASC 840. As we are electing the package of practical expedients, these leases will continue to be classified as operating leases subsequent to the adoption of ASC 842. On January 1, 2019, we will record a lease liability and a right-of-use asset for these leases on our consolidated balance sheets and on a go-forward basis, lease expense will be recognized on a straight-line basis over the remaining term of the lease. See Note 10 for a summary of rent expense and remaining contractual payments under our ground lease and office space leases. ASC 842 requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases, and operating leases. ASC 842 specifies that payments for certain lease-related services (for example, maintenance services, including common area maintenance), which are often included in lease agreements, represent “non-lease” components that will become subject to the guidance in ASC 606 when ASC 842 becomes effective. ASC 842 provides lessors with an optional practical expedient, to elect to not separate non-lease components from associated lease components (the “non-separation practical expedient”) if both of the following criteria are met: (1) the timing and pattern of transfer of the lease and non-lease component(s) are the same and (2) the lease component would be classified as an operating lease, if it were accounted for separately. If both criteria are met, the combined component is accounted for under ASC 606 if the non-lease component is the predominant component of the combined component; otherwise, the combined component is accounted for as an operating lease under ASC 842. On January 1, 2019, we elected the non-separation practical expedient as part of our adoption of ASC 842. We anticipate that the majority of our leases will qualify for the non-separation practical expedient. Additionally, ASC 842 requires lessors to capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. As a result, compensation costs related to employees who spend time on lease origination activities, regardless of whether their time leads to a successful lease, will no longer be capitalized as initial direct costs and instead will be expensed as incurred. See “Deferred Leasing Costs” above for a summary of employee related compensation costs capitalized during the years ended December 31, 2018 , 2017 and 2016 .
